Briefly statedmyapparatustconsists of an uprightV frameforrholding thecopy sheet the frame takes the form of a light metal; rectangular box 1enclosed by a sheet metal before the eyes of an operator with meansv foradvancing thesheet line by line and a set of magnitiers or mirrors forthrowing anH enlarged image of each `line to the observer.

ln the embodiment shown in the drawing front plate 2 and a similar rearplate 3.

To insure the frame standing upright on a desk. l provide a hinged footl at the front of the frame and which may be folded iiat against theframe as indicated at 5 when not in use.

This foot preferably has a lower flange l to bear against the desk 6 anda screw hole 7y so that it may be screwed to the desk ifdesired.

will frictionallygrip Ythe roll and revolve`it'f slightly, but uponbeing pushed upwardly will slide over the roll on account of the rolllbeing locked` against reverse movement by the ratchet 13.v

To pull the rod downward, it is pivotedv at its lower end to a rockerarm 31-'c'a-rried by the frame andtheouter end of the rockerV armprojecting through a slot 32 in the rear plate 3 is pivoted to a link33'in turn pivoted to a hand lever 34 which in its turn is pivoted tothe sideof the frame at 35 so that by mov- :roller carried thereby, amember yieldingly ing the hand lever the link 33will be forced upwardand will pull the rod 29 downward to revolve the roll'8.

The rod'is returned by aspring36 hooked to the top of the frame and to abracket 37 'm secured to the rod, and the bracket extends in the form ofa binding post 38 througha slot` 39 in the side of the frame for thereception of a wire 40 secured by a thumb screw 41 in the end of thepost. n omitted from Figure 2 to prevent confusion.)

This wire 40 is preferably a small cable and extendsV along side thedesk, or through a small hole drilled through it7 to the floor.

where it connects topa foot pedal 42 (see i Figure 5) hinged at 43'toasupporting board 44 preferably equipped with spikes or pins 45 to keepit from slipping out of place.

In setting the device, the wire is pulled through the bindingpost 38until the pedal 42 is lifted as shown and then the wire is firmlysecured to the post by the screw 41 with the arrangement described apressure ofthe foot on the pedal pulls the rod 29 and advances theroll8.

it will be apparent that many modications in the mechanical details maybe made without departing from the spirit of the invention, and any suchare-intended to be em- `braced in my' appended claims.
